//  This file creates a global JSON object containing two methods: stringify

//  and parse. This file provides the ES5 JSON capability to ES3 systems.

//  If a project might run on IE8 or earlier, then this file should be included.

//  This file does nothing on ES5 systems.



//      JSON.stringify(value, replacer, space)

//          value       any JavaScript value, usually an object or array.

//          replacer    an optional parameter that determines how object

//                      values are stringified for objects. It can be a

//                      function or an array of strings.

//          space       an optional parameter that specifies the indentation

//                      of nested structures. If it is omitted, the text will

//                      be packed without extra whitespace. If it is a number,

//                      it will specify the number of spaces to indent at each

//                      level. If it is a string (such as "\t" or "&nbsp;"),

//                      it contains the characters used to indent at each level.

//          This method produces a JSON text from a JavaScript value.

//          When an object value is found, if the object contains a toJSON

//          method, its toJSON method will be called and the result will be

//          stringified. A toJSON method does not serialize: it returns the

//          value represented by the name/value pair that should be serialized,

//          or undefined if nothing should be serialized. The toJSON method

//          will be passed the key associated with the value, and this will be

//          bound to the value.



//          For example, this would serialize Dates as ISO strings.



//              Date.prototype.toJSON = function (key) {

//                  function f(n) {

//                      // Format integers to have at least two digits.

//                      return (n < 10)

//                          ? "0" + n

//                          : n;

//                  }

//                  return this.getUTCFullYear()   + "-" +

//                       f(this.getUTCMonth() + 1) + "-" +

//                       f(this.getUTCDate())      + "T" +

//                       f(this.getUTCHours())     + ":" +

//                       f(this.getUTCMinutes())   + ":" +

//                       f(this.getUTCSeconds())   + "Z";

//              };



//          You can provide an optional replacer method. It will be passed the

//          key and value of each member, with this bound to the containing

//          object. The value that is returned from your method will be

//          serialized. If your method returns undefined, then the member will

//          be excluded from the serialization.



//          If the replacer parameter is an array of strings, then it will be

//          used to select the members to be serialized. It filters the results

//          such that only members with keys listed in the replacer array are

//          stringified.



//          Values that do not have JSON representations, such as undefined or

//          functions, will not be serialized. Such values in objects will be

//          dropped; in arrays they will be replaced with null. You can use

//          a replacer function to replace those with JSON values.



//          JSON.stringify(undefined) returns undefined.



//          The optional space parameter produces a stringification of the

//          value that is filled with line breaks and indentation to make it

//          easier to read.



//          If the space parameter is a non-empty string, then that string will

//          be used for indentation. If the space parameter is a number, then

//          the indentation will be that many spaces.



//          Example:



//          text = JSON.stringify(["e", {pluribus: "unum"}]);

//          // text is '["e",{"pluribus":"unum"}]'



//          text = JSON.stringify(["e", {pluribus: "unum"}], null, "\t");

//          // text is '[\n\t"e",\n\t{\n\t\t"pluribus": "unum"\n\t}\n]'



//          text = JSON.stringify([new Date()], function (key, value) {

//              return this[key] instanceof Date

//                  ? "Date(" + this[key] + ")"

//                  : value;

//          });

//          // text is '["Date(---current time---)"]'



//      JSON.parse(text, reviver)

//          This method parses a JSON text to produce an object or array.

//          It can throw a SyntaxError exception.



//          The optional reviver parameter is a function that can filter and

//          transform the results. It receives each of the keys and values,

//          and its return value is used instead of the original value.

//          If it returns what it received, then the structure is not modified.

//          If it returns undefined then the member is deleted.



//          Example:



//          // Parse the text. Values that look like ISO date strings will

//          // be converted to Date objects.



//          myData = JSON.parse(text, function (key, value) {

//              var a;

//              if (typeof value === "string") {

//                  a =

//   /^(\d{4})-(\d{2})-(\d{2})T(\d{2}):(\d{2}):(\d{2}(?:\.\d*)?)Z$/.exec(value);

//                  if (a) {

//                      return new Date(Date.UTC(+a[1], +a[2] - 1, +a[3], +a[4],

//                          +a[5], +a[6]));

//                  }

//              }

//              return value;

//          });



//          myData = JSON.parse('["Date(09/09/2001)"]', function (key, value) {
